srEcIFIcATIoN forming part of Letters Patent No. a'3,449da.tea July 24, 1894. Application filed August ,71893. Serial No. 483.234. (No model.)

:To all whom it may concern:

Be it known that I, OSCAR G. AHLSTROM, of New York city, in the county and State of New York, have invented a new and Im proved Bottle-Stopper, of which the following is a full, clear, and exact description.

This invention relates to the class of stoppers that are to be used in bottles `containing liquors, which shall be so constructed and arranged that the contents thereof may be freely poured out, but it will be impossible to refill the same without destroying the effectiveness of the stopper, which is to be permanently attached within the bottle.

The construction and operation of my bottle-stopping device will be fully shown and described in the following drawings and specification.

The in vention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding par-ts in all the figures.

Figure l is a sectional front view of a bottle furnished with my stopper device, showing the same when closed. Fig. 2 is a sectional front view'of the same, showing the bottle inverted and the stopper in position while the contents are being poured out; and Fig. 3 is a sectional front view of the valve and the device for holding the same in position to slide up and down in the act of opening and closing the stopper, and a section of lthe shell in which it is inclosed.

In the drawings A represents the neck of a bottle which is provided with the lugs a a, and the Ilange a.

B represents a jacket of cork enveloping the metallic shell d of the stopper device, which said jacket extends from a point b to the bottom of the same, the space b', being lled with sealing wax, upon lwhich is impressed a suitable seal. The valve or stopper C, is inserted in the portion D, its stem passing through the guidel holes c, c, of the .s same, which is then placed in position inside points o. a, being pressed into the cork, and the wax seal will prevent the removal of the stopper without injuring or destroying the same.

E is the inlet orifice, and E the outlet.

The usual cork stopper is inserted at It will be seen that the peculiar construction of the valve-carrying and holding portion D, renders it impossible to raise the valve from the outside, as no access can be hadto the valve stem, and the Weight of the valve itself running easily inthe guide holes will by its gravity close the orifice E', as soon as the bottle is in a perpendicular position, so that the bottle cannot be refilled While the said device is' in it. The arrows show the course of the liquid while being poured out.

It is intended that all the parts composing the stopper shall be made of very thin material, so that any tampering with them will destroy their eiiectiveness, and this also adds cheapness to its other advantages over any stopper known to me, for the stopper is not to be used again when the bottle is emptied.

To pour out the contents the bottle is tilted or inverted, and the valve by its gravity slides downward and away from its seat, and permits the liquid to flow out as indicated by the arrows.

I am aware that automatic valve Stoppers for bottles have been patented and I do not claim broadly such a construction. s

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a bottle stopper consisting of the interior portion D. provided with valve C; parts having guide holes c. c. for the stem of the valve C, and a diaphragm to prevent access to said valve stem,I said interior portion D. f
